Answer:

The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.

Explanation:

Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.

Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.

WARRIOR [948]

Answer:

3:1

Explanation:

To find out the phenotypic ratio, we need to do a Punnet Square.

We know that R and I are the dominant alleles that produce red flowers, and r and i are the recessive traits.

<u>  ║R ║ r</u>

<u>I ║RI║Ir</u>

<u>i ║Ri║ir</u>

The genotype ratio would be 3 because the dominant traits are present three times (RI, Ir, and Ri) and 1 for the recessive trait since it only appears once in the Punnet Square (ir). In conclusion, the phenotypic ratio form the roses are 3:1
